The least common denominator of 12, 8, and 36 is 72.
Answer:
The last two functions are decreasing!
Step-by-step explanation:
You can easily tell the functions are decreasing if the function is going down from L to R. If it is going up, from L to R, then it is increasing!
One number: x
Its consecutive: x + 1
Product:
x(x+1)=121
x² + x - 121 = 0
Δ = 1² - 4.1.(-121)
Δ = 1+484
Δ = 485
As square root of 485 is not integer, do not exist two consecutive numbers with product of 121
Answer:
x=3 y=0
Step-by-step explanation:
Answer: 7.7 miles
Step-by-step explanation:
2.5x + 5.75 = 25 (<em>x = each mile traveled)</em>
2.5x = 25 - 5.75
2.5x = 19.25
x = 7.7 miles
